Preservationism, or The Elephant in the Room: How Opponents of Same-Sex Marriage Deceive Us into Establishing Religion
The overwhelming majority of support for bans on same-sex civil marriage has come from religious believers, and the so-called secular justifications for these bans are mere pretexts for religious beliefs that homosexuality, homosexuals, and same-sex couples are evil or sinful. Courts should take a hard look at the substantive justifications offered in support of same-sex marriage bans, bearing in mind that (1) these justifications are universally offered by religious believers but are infrequently offered by credentialed Secularists, and (2) they are the result of a studied use of pretextual, secular-sounding language to cloak a religiously-motivated bias against homosexuals and same-sex couples

South Asian Americans in Higher Education: Background and Future Directions
South Asian Americans are one of the fastest-growing ethnic groups in the United States. Though research has broadly attended to Asian Americans as an aggregate racial or ethnic group, calls to specify the complex experiences and identities within this group have increased. This is particularly true for South Asian Americans, or Desi, groups as their ethnic and cultural identities have been increasingly scrutinized and racialized since September 11th. This backgrounder discusses South Asian Americans within higher educational institutions. More specifically, I provide an overview of identity development models, contextualize their unique challenges, and relate these models to South Asian Americans. The backgrounder concludes by outlining opportunities for supporting South Asian American students in higher education.Educatio
Eliminating flutter for clamped von Karman plates immersed in subsonic flows
We address the long-time behavior of a non-rotational von Karman plate in an
inviscid potential flow. The model arises in aeroelasticity and models the
interaction between a thin, nonlinear panel and a flow of gas in which it is
immersed [6, 21, 23]. Recent results in [16, 18] show that the plate component
of the dynamics (in the presence of a physical plate nonlinearity) converge to
a global compact attracting set of finite dimension; these results were
obtained in the absence of mechanical damping of any type. Here we show that,
by incorporating mechanical damping the full flow-plate system, full
trajectories---both plate and flow---converge strongly to (the set of)
stationary states. Weak convergence results require "minimal" interior damping,
and strong convergence of the dynamics are shown with sufficiently large
damping. We require the existence of a "good" energy balance equation, which is
only available when the flows are subsonic. Our proof is based on first showing
the convergence properties for regular solutions, which in turn requires
propagation of initial regularity on the infinite horizon. Then, we utilize the
exponential decay of the difference of two plate trajectories to show that full
flow-plate trajectories are uniform-in-time Hadamard continuous. This allows us
to pass convergence properties of smooth initial data to finite energy type
initial data. Physically, our results imply that flutter (a non-static end
behavior) does not occur in subsonic dynamics. While such results were known
for rotational (compact/regular) plate dynamics [14] (and references therein),
the result presented herein is the first such result obtained for
non-regularized---the most physically relevant---models
Higher spin polynomial solutions of quantum Knizhnik--Zamolodchikov equation
We provide explicit formulae for highest-weight to highest-weight correlation
functions of perfect vertex operators of at
arbitrary integer level . They are given in terms of certain Macdonald
polynomials. We apply this construction to the computation of the ground state
of higher spin vertex models, spin chains (spin XXZ) or loop models in
the root of unity case
